Madison Square Garden Entertainment Corp. (MSG) recently experienced a data breach that involved sensitive personal information of 11 Maine residents. The breach was tied to the Oracle eBusiness Suite, a system hosted and managed by a vendor used for workforce and financial operations. A previously undisclosed vulnerability in the Oracle application allowed unauthorized access to business records, including names and Social Security numbers. If you were affected, you may be eligible to join a class action lawsuit for compensation.

Madison Square Garden’s Data Breach Investigation

The breach stemmed from the Oracle eBusiness Suite, which MSG uses for managing its workforce and financial operations. A vulnerability within the application was exploited by an unauthorized person to access data from over 100 companies, including Madison Square Garden. The breach occurred sometime between August 10, 2025, and October 21, 2025, but it wasn’t until late November 2025 that an investigation revealed the unauthorized access.

Upon discovering the breach, MSG immediately began investigating, working alongside a forensic firm to analyze the extent of the compromise. By December 2025, MSG reviewed the files involved in the breach and identified that a file containing the names and Social Security numbers of 11 Maine residents had been exposed. The breached files were part of business records related to hiring or payments made to individuals.

In response, Madison Square Garden notified affected individuals and offered one year of complimentary credit monitoring and identity protection services. The vendor also implemented additional measures to prevent similar breaches in the future, following recommendations from Oracle.
